AFL investigators are at the Adelaide Crows to scrutinise the club's books in their probe into the Kurt Tippett controversy.
Investigators arrived at the Crows' West Lakes headquarters on Friday morning as they continue to explore the circumstances surrounding Tippett's deals with his former club.
New twist in Tippett probe
The AFL investigation into alleged draft tampering by Adelaide broadens to include accusations of salary cap cheating.
Tippett faces possible deregistration as an AFL player and the Crows could be fined and lose draft picks after admitting they had a secret deal with the star forward, who wants to be traded to Sydney.
But with Friday's 2pm AEDT deadline in trade dealings looming, Tippett is expected to remain without a club.
The 25-year-old would then be pitched into the draft, where the Swans may be trumped by rivals to secure his services, with Brisbane believed to be ready to swoop on the ruckman-forward.
The Crows last Friday confessed to the AFL they struck a 2009 deal with Tippett and his management to trade him to the club of his choice for a second-round draft pick.
The deal is also believed to include an agreement to pay Tippett an extra $200,000 when his contract expired.
Tippett became Adelaide's highest paid player when re-signing in 2009 for three seasons in a contract now expired.
But the secret deal outside the contract prompted an AFL investigation into the matter, which could lead to heavy sanctions against the Crows.
Adelaide's chief executive Steven Trigg's future at the club is also in jeopardy given he was a key figure in brokering the deal kept secret from the league.
AFL officials arrived at Adelaide's headquarters to claim material for the league's investigations officer Ken Wood and integrity officer Brett Clothier.
The AFL has not put a timeframe on completing its investigation.
